PixLite 16 User Manual V1.2

The hardware test requires that the pixel driver chip type and number of pixels per output are set
correctly in the PixLite configuration. In this way you can test if that part of your configuration is
correct and isolate other possible problems with the incoming Ethernet data side.

Auxiliary Output
The controller features an auxiliary output that can power an external fan(s) for cooling the
enclosure that the controller is mounted in. This output is located on the far left edge of the board
and is show in figure 8. This feature is useful in order to keep the temperature regulated when you
mount the control board and a high wattage power supply together in a small, confined space.
The output voltage of the auxiliary power is taken from the Bank 1 voltage input. So to run a 12V fan
for example, you would need to use a 12V input voltage for your Bank 1 supply. The auxiliary output
can supply up to 15W of continuous output power, and is PWM controlled.
Basic operation is as follows: In the Assistant configuration software (see the PixLite Configuration
Guide), the user can set a target temperature that the enclosure will ideally not exceed. The
controller will then automatically adjust the fan speed based on the current temperature as
measured by the
controller’s
on-board temperature sensor.
For example, if the target temperature is set at 30°C then sometime before that temperature, the
controller will turn the fan on and slowly ramp up the speed until it reaches 100% if required, in an
attempt to maintain the temperature either at or below 30°C. If the temperature were to then
slowly drop back down then the fan will also reduce speed until it switches off completely. The same
process will be repeated if the temperature begins to rise again.
If the detected temperature reaches the set temperature, the fan output will be on 100% at this
point.
